when we were young, we r always headstrong, impulse and we often do something which we like without thinking. when we grow up, we have more responsibility, take in account the feelings of people around us. dont be childish any more, we must think abt consequences and listen to other people's advices before we make decisions, think abt if it is right or not, if it will hurt others or not. Of course, there is something we can not predict the results are right or wrong, and sometimes we feel that there is something we must to do , then just do it ,the facts will tell us right or wrong. people becomes mature with such an environment . remember, everything has price to pay, worthing or not, it's up to you. bt if u decide to do , u must accept all the results no matter right or wrong, good or bad, you cant complain others, coz it's your own choice
